Specification of Letters Patent.

Applicationfiled June 2'7, 1911, Serial No. 635,590. Renewed September 16, 1913. Serial No. 790,108.

To all whom it may concern Be it known that I, SAMUEL W. CHARLES, of the city of Palo Alto, in the county of Santa Clara, State of California, have invented new and useful Improvement in Bazor-Stropping Devices, of which the following is a specification.

My invention relates to improvements in razor stropping devices whereby the razor blade may be correctly stropped without removing the blade from its holder in the razor frame.

The primary object of my invention is to provide a razor stropping device whereby the blade in a safety razor may be correctly st-ropped without removing the blade from its holder inthe razor frame.

The invention consists in the construction and arrangement of parts which will be fully hereinafter specified in preferred form.

In the drawing Figure 1. is the top plan view of a razor stropping device embodying the features of the invention, in position on the strop for stropping. Fig. 2 is a side view corresponding to Fig. 1 except that the near half of the pulley clip is removed. Fig. 3 is a partial rear view of the razor stropping device wit-h pulley clip attached, one end of the clip being thrown into side elevation to show the square hole in the pulley. Fig. 4; is a view of the strop showing the pulley clip on the cords.

The constituent parts of the razor stropping device are the supporting frame A to which are attached the handle B and combed guard plate C.

D is a shaft and is free to turn in frame A. The blade is designated I and is held in a recessed seat in blade holder H. The blade holder H is rigidly attached to shaft D. The blade I is held against the guard G in position for shaving by movable latchfingers G, the hooked ends of which project over each corner of the blade. The latch fingers are held in locking position by spring K which is fastened to handle B. The blade is released by pressing together the two latch handles J which spread apart the fingers G. The blade I may be then swung clear of the guard plate C for stropping.

fastened to handle R which is separate from handle S of the strap. V

T is asteel frame or steel clip of spring material. Held in this clip are two pulleys Fwhich are free to rotate in the clip and have square holes through their centers to engage the projecting ends of shaft D which are squared to receive them. The clip is attached to the strop by wrapping the cords once around their respective pulleys in such a manner that the cords approach and leave the pulleys at the top asshown in Figs. 1 and 2.

To strop the razor, the blade I is released by pressing together the two latch handles J which spread apart the latch fingers G. The supporting frame is then placed in the pulley clip by slipping its handle B through the hole U and springing apart the pulleys F so that the squared ends of shaft D may be-fitted into the squared holes in pulleys F.

The spring of clip T will hold the squared L and grasp in one hand the two handles R and S. With the other hand move the supporting frame forward and backward along the strop by means of its handle B. The action of the cords on the pulleys causes the blade to extend in the direction opposite to that in which the supporting frame is moving and to be dragged in stropping position along the strop N. The pressure of the blade against the strop is regulated by the tension put upon the cords by the hands holding them. Upon reaching the end of a stroke the return stroke is begun but the action of the cords upon the pulleys is such that the blade is swung into proper position the instant the return stroke is begun. The swinging of the blade upon a reversal of the stroke is positive and timely thus effectually preventing any cutting of the strop. The supporting frame may be removed from clip T by springing apart the pulleys F and disengaging the squared ends of shaft D from the pulleys. a

The drawing shows the cords wound once around the pulleys but they may be wound more than once. The pulleys are shown to be cylindrical and flanged but they may be of irregular shape and roughened or corrugated to offer greater friction to the slipping of the cords on their faces. The flanges may be entirely omitted.

. thereon, of a strop, a reciprocatory carrier mounted on the strop, a rotatable device actuate the latter upon the combined reciprocation ofthe frame and carrier.

' described above. v the details of construction may be varled detachably connecting the rotatable device 'tothe oscillatory blade holder to cause the the combination with a supporting frame The projecting ends of shaft D may be triangular, polygonal or of irregular shape in which event the holes in the pulleys must be made to match.

I do not limit myself to the exact details It will be understood that slightly to facilitate or cheapen the manufacture.

Having thus described the nature and objects of my invention and the manner of ts operation, What I claim as neW and desire to secure by Letters Patent 1s,

1. In mechanism of the character set forth, the combination with a supporting; frame and an oscillatory blade holder mounted j ournaled on thecarrier, means for causing the rotation of the device upon the reciprocation of the carrier, and means for detaclr ably mounting the frame on the carrler and former to actuate the latter.

2. In mechanism of the character set forth,

the combination With a strop and a cord disposed longitudinally thereof, of a reciprocatory carrier associated with the strop, a roller journaled on the carrier and engaged with the cord, an oscillatory blade holder, a supporting frame, having means for detachably mounting the supporting frame on the carrier with the blade holder in detachably clutched engagement with the roller.

4:. In mechanism of the character set forth, the combination with a strop and spaced cords disposed longitudinally thereof, of a reciprocatory carrier associated with the strop, said carrier having an opening and relatively movable side arms, rollers journaled on the side arms and having angularsockets, said rollers being engaged with the cords, and a supporting frame, including a handle that detachably engages in the opening of the carrier, a rock shaft having projecting angular ends that detachably engage in the sockets of the rollers, and a blade holder mounted on the rock shaft.

5. Inmechanism of the character set forth, the combination with a strop, of spaced cords disposed longitudinally thereof, a carrier frame that reciprocates along the strop, said carrier frame having spring arms, rollers ournaled on the spring arms and having engagement with the cords, said rollers having angular sockets in their inner ends, and means for detachably mounting a supporting frame on the carrier with the bladeholder thereof detachably engaged With the rollers.
